The purpose of this study was to compare hip and knee biomechanical and metabolic differences among elliptical exercises and running in healthy runners. Sixteen participants were tested on three different exercise conditions (treadmill running; TR, standard elliptical; SE, lateral elliptical; LE). Hip and knee kinematic (i.e. angular motion) variables were measured using a motion capture system, and a metabolic system was used to measure metabolic cost (i.e. VO2, caloric cost, RER). Sagittal knee ROM was greater in LE and SE compared to TR. Hip abduction and external rotation ROM were greater in LE compared to SE and TR. Similar metabolic cost were produced during LE compared TR; LE and TR produced greater metabolic cost than SE. The general findings suggest LE produces knee and hip joint kinematics opposite of reported joint kinematics in runners with AKP and yeilds similar metabolic cost compared to TR.
